Yeah, sure, but that sort of thing's going to happen with mythological references if you dig deeply enough. Here's a few choice selections, including a couple of rather prominent 'Mechs:
The Atlas is named for a fellow who carries the weight of the sky on his shoulders for backing the wrong side in a divine power grab. Considering that it was built by the dominant side at the time - a side justifiably comparable to the mythological Titans - one could argue that Kerensky was asking for it. The strength is notable, of course, but so is the might and ferocity of the legendary Amazons.
The various stories around the constellation Cygnus aren't the most inspiring things ever. The kid who committed suicide stands out pretty nicely and I can't say a murdered bard is particularly cheerful, either. Achilles had a hand in defeating another guy transformed into a swan.
The Fafnir was named for a guy turned into a dragon for his sheer greed (a greed that inspired him to murder his father) and who ultimately lost his treasure anyway after being the subject of a fratricide. Greatly inspiring, huh?
The Goliath was named for a well-known figure who lost to a lucky shot with a sling. No one really remembers him for anything else most of the time.
Imps are small, mischievous demon, so of course they're the perfect thing to name a 100 ton command 'Mech after.
